Abstract
EL INVENTO ES UN PROCEDIMIENTO PARA CODIFICAR Y DESCODIFICAR INFORMACIONES POR BLOQUES, ESTANDO CONSTITUIDO CADA BLOQUE PR UN NUMERO FIJADO DE VOCABLOS DE INFORMACIONES QUE COMPORTAN CADA UNO N BITS, COMO MAXIMO Y LA POSICION DE LOS VOCABLOS EN CADA BLOQUE ESTA MARCADA POR UNA SERIE DE DIRECCIONES, LLAMADAS ABSOLUTAS, CON UNOS VALORES CONSECUTIVOS. EL CODIFICADO CONSISTE EN: -CLASIFICAR LOS VOCABLOS DE INFORMACION EN N CLASES N I, PARA I=1 EN N, LA CLASE N I REAGRUPA TODOS LOS VOCABLOS CON I BITS SIGNIFICATIVOS, -TRANSMITIR,CLASE POR CLASE, LOS VOCABLOS QUE NO TIENEN UN VALOR NULO , OMITIENDO EL BIT SIGNIFICATIVO DE MAS FUERTE PESO, Y CADA VOCABLO ACOMPAÑADO DE LA DIRECCION, LLAMADA DIRECCION TRANSMITIDA QUE SE CALCULA A PARTIR DE LA DIRECCION ABSOLUTA DEL VOCABLO TRANSMITIDO, SUSTRAYENDOLE LA DIRECCION ABSOLUTA DEL ULTIMO VOCABLO QUE HA SIDO CODIFICADO PROCEDENTEMENTE EN LA MISMA CLASE, Y SUSTRAYENDOLE UN NUMERO DQUE ES IGUAL AL NUMERO DE VOCABLOS QYUE AHN SIDO CODIFICADOS PRECEDENTEMENTE EN TODAS LAS CLASES CON UN NUMERO INFERIOR A AQUEL DE LA CLASE DEL VOCABLO CONDIDERADO, DESDE EL ULTIMO VOCABLO QUE HA SIDO CODIFICADO PRECEDENTEMENTE EN LA MSIMA CLASE. EL VALOR DE LAS DIRECCIONES TRANSMITIDAS SE CODIFICA A CONTIINUACION POR UN CODIFICADO DE LONGITUD VARIABLE TAL COMO UN CODIFICADO DE HUFFMANN.
